All
I have been testing DSU backups, and must admit I have not been impressed
with the throughput to disk.
 
I ran a particular job over the weekend. Setup as follows:
 
LAN Client normally takes 2-3hours via Tape LTO3 HP ESL
Created a Disk on my Master Server
Configured a DSU with phase 2
Set the policy to use the newly created storage unit.
Let the backup run.
 
The backup took 4 hours (just over). However, writing to tape (I guess when
it does its duplication) took under 1 hour.
 
The Disk that was presented to my Master is a VDISK from a HP EVA using
Fibre SCSI disks. Essentially the HP EVA is a large SAN, and you can create
volumes and present them to a specific Server.
 
Have I missed something here, or is it a case that my Tape Setup (that is
all fibre channel connected) is actually running better than I thought.
 
Thanks
